Main features of power spindle:

1. Higher dynamic

2. Low vibration

3. Rated power 9,5 kW – 23,4 kW

4. Rated torque 45Nm – 89,4 Nm

AMS type motors can call as compact power spindle, because these integrated to a lathe spindle. Their dynamic rigidity and low vibration tendency make a further leap in machining quality.
ADVANTAGES OF POWER SPINDLE OPPOSE TO CONVENTIONAL BELT DRIVE:
- Higher dynamics because of smaller inertial mass, lower loss, lower current drain
- Better workpiece geometry thanks to the lack of deformation caused by belt tension
- Higher lifetime, better surface quality on workpiece and higher tool edge life thanks to much lower vibration level
- Better workpiece geometrical and repeating accuracy, longer lifetime of bearing thanks to lower heat deformation because of high liquid cooling.
